AUTOMOBILELAMP.

Application filed January 10, 1921. Iseria1 no; 436;10s.

To all whomit may cancer n1 'Be it known that LiOLA E. ALLEN, a citizenof-the United Statearesidinglat Cleveland, in the county of Cuyahoga andState of Ohio, have invented acertain new and useful Improvement inriAutomobile Lamps, of which the following isa full, clear, and exactdescription, reference being had to the accompanying drawings.

This invention relates generally to lamps, and more particularlyto; oneiintendedfor use upon motor vehicles; and'the object of the invention isto provide 1 certain novel means for securing the reflector andglass inthelamp body so as to avoid'rattling.

Anotherobjeot of the invention iss'to provide means for connectingthese'parts, independently, vthat is, means for connecting the reflectorto the lamp ibody,*zseparate means for connecting the glass to thereflector; and-still further independentmeans for securing all withinthe lamp-body: I p v A still further object is to provide certainimprovements in these parts whereby they may be quickly and easilyarranged wvithin, or removed from, the. lamp body; and a still furtherobject is to provide anovel construction of ring fasteningameans so thataccess to the lamp for the purpose ofc'leaning the same, orreplenishingthein'candescent bulbs can be quicklyiandeasily accom-Plished. 1

- With these various objects in view, theinvention consists in certainnovel' features of construction and also in the manner of combining orarranging s'aidflparts', all of which will be fully describedhereinafter and pointed'out in the claims. 1' 1T In the drawings forminga partofzthis specification Fig. 1 is a face view partly inv section ofa lamp embodying my invention;

2-2 of Fig. 1; Fig. 3 is a detail view showing a portion of the lampbody; Fig. 4 is a similar view of a portion of the reflector;

Fig. 5 is a section on theline 55 of Fig. 1. j-

thereby efi'ecting' the connection of the reflector through the'lampqbody. 'Thegbow" I e axially extending circumferential :flange '11.

This sheet metal'body portionmay. be provided with any suitable form ofattaching bracket; and is also provided with socket connections for themain and the auxiliary or d mmer" ncandescentlights; I

The clrcumferential flange is provided with radial inwardly projectinglugs 12 preferably at equidistant v points, said lugs' being formed bypunching the: metal in- 'wardly, and :the circumferential flange is alsoformed, preferably atequidistant points Inetalinwardly, and'in additionto theseries ing in the fOIIIl Of an inwardly extending receiving :the;auxiliary or dimmer light. 2

"with inwardly extendin ears 13 which are I also preferably-formecfbypunching 'the bow having the ends 15 thereof turnedfto enter theinwardly projecting ears-13. f 1 :The reflector l6fis preferablyofparabolic type and has a central opening, to ,7 receive the socket ofthe main light; and is also4pr'ovided at the proper placewitharsocketfor At: the outer edge of theparabo1oid,-t'he reflector isformed with a circumferential, beadl? which is substantiallyrectangularin cross section :andprojecting outwardly from this head is, theradiallyv extending ,cir-

cumferential flange 18 and the flangawith reflector isofv such size astofit snugly within the circumferential axial edge or :flange portion'll:of; the lampv body, and the circumferential flange 1810f the reflectorcontacts with and bears upon the springs 15 carried by the lamp body 10.i

T Atxdefiniteupoints, the reflector, flange'eis provided with notches 19throughgwhich the l I inwardly projecting lugs 12 of-the lamp body areadapted, to pass,.and'thenby giv- I in'g thereflector a slightcircumferential fmovement, the flange thereof can. be moved beneath theinwardly. projecting lugs 12 springs 15 carried byythe body beingsubjected to tension andacting as they deconstantly upon the flange ofthe reflector hold 5 the reflector and body in locked relationandprevent rattling. In practice I prefer to upset the flange 18 at onepoint 20 adjacent one of the notches 19 in order to limit thecircumferential movement of the reflector flange beneath the radiallyinwardly pro- .ojectinglugs.

' Thereflector flange is provided with a plurality, (preferably three)hooks or retaining members 21 each one comprising a portion whichextends axially outwardly, and a portion which extends radiallyinwardly, and the lass can be inserted from one side and brought intoengagement with said hooks or retaining members, and the periphery oredge of the glass will contactwith v the axially extending portions,while the radially extending "portions overlap the edges of said glassand prevent any movement-thereof. In practice,-I prefer to arrange acushion ring'22'of anysuitable materiallupon the outer face of the headof the reflector and against which'the inner face of the glass willcontact.

Inorderlto hold the glass inrplace upon the reflector, and also toeflectively close the -.outer or front edge of the lamp body, I pro- 1vide a sheet metal ring 23 whichis flanged or channel shaped-in crosssection, the inwardly projecting edge thereof being adapted to contactwith the outer face of theglass,

'and the outwardly projecting edgethereof being adapted to pass aroundand envelop 1 the outer or forward edge of the body; and

in placing thisring upon the body it is first inserted over theoutwardly projecting lugs 24 and then brought over the opposite side ofthe "lamp body, and in order to secure the locking ring in engagementwith the lamp body,

and the outwardly projecting lugs-in par- ]ticular, -I employ a latch25within thelamp body and having its outer curved or hooked end 25 workingthrough an opening 26 prolatch contacts with a bow spring 28 held inplace bythe additional pair of'inwardlyprojec'ting ears 1% and, as thescrew is tightened to project the outer curved or hooked'end of thelatch outwardly, the central portion of the spring is-p'ressed inwardlyand exerts a constant pressureupon the latch, so that when the screw isloosened, the outer end of "the said latch will beimmediately forcedinwardly inside the'lamp body so that the ad jacent portion of the ring23 can be lifted "clear of the edge bf the'lampbody, and after that sideof the ring has been cleared, a

slight movement of the ring will carry the opposite side away from, andout of engagement with, the outwardly projecting lugs 24,. andthe ringwill be then entirely clear of the lamp body. v

The glass, however will remain in its proper position upon the front ofthe reflector, being held thereby the hooks or'reta'ining membersQL' aBy removing the ring and glass, access can be had to the lamp for thepurpose of cleaning thereflector or; replenishing the lights, and incase it is desired to remove the reflector itself, it is only-necessaryto first remove the main incandescent llght, and then give thereflectora slight'rotary movement, so as to bring the notched edgesthereof;19-op tween the body and reflector and therebyeliminate rattleat this point, and the ring securely holds the glass, in place'upon theY cushion ring of thereflector and consequently all rattle at: thesepoints is eliminated.

carried by the lamp posite the inwardly projecting lugsxl2;-and

The various features of constructionherein set forth lend themselvesreadily to reduce the cost of production in providing a highly eflicientand easily manipulated headlight lamp for motor vehicles.v

Instead of employing be provided, or any other suitable bolt or latchactuating device mayt be employed;

an ordinary screw,' to operate the latch, I may provide said screw w1thamilled head; orv a wing nut may and it will also be understood that:certain changes or modifications imay bev made with reference totheother details of construction within the scope of .the' ap ended claims;I

Having thus describe my r invention,

' lamp body for limiting the inwardmovean axial circumment of thereflector, and'springsuattached to the axial edge of the lamp body andadapted to engage the flange of the reflector, a glass held in contactwith said reflector, a

ring, engaging the outer face of the glass and I the exterior of thelamp body, and a latch I arranged uponthe interior of the lamp body .atone side, and a screw working through the lamp body and adaptedto'actuate said latch to-holdthe ringiinplace.
